Abstract

PURPOSE:To cause strong power to be unnecessary for a center pin in order to obtain long durability life of said pin by following method in which a mold-cavity is formed by lowering a double cylinder like annular body with inner and outer walls and an upper cover of this annular body onto a lower stand, and the raw material for cake is poured into said cavity. CONSTITUTION:According to lowering an upper stand frame 10, a sliding transverse frame 13 being in contact with the stopper 7a of a rod 7 is also lowered. Next, the sliding transverse frame 13 is caused to be in contact with a stopper 12 and consequently its lowering is stopped, and further an upper cover 12 equipped to the lower part of a rod 11 is stopped in a predetermined position. In spite of the stop of the sliding transverse frame 13, the upper stand frame 10 is continued to be lowered with stretching a tension-spring 15 , and it is stopped when it becomes in contact with lower stands 3 and 4a. At this state, the dough-nut like cavity enclosed by the lower stand 3, 4a, the annular internal wall 10, the annular external wall 10b and an upper cover 12, is formed. According to the stop of said sliding transverse frame, an operative piece 13a equipped on its side pushes a switch 14, thereby pouring the raw material for the cake from the injecting port communicating with said cavity. Thus, the toroidal type cake is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing a cake for large-pore disks.

Conventional cakes did not have a hole in the center, so when forming a disk, the material in the center of the cake was pushed away with a center pin to press-form a disk with a large hole.

However, this method requires a strong force to push away the material from the center of the cake, and the material cannot be completely pushed away, leaving a thin film behind, which is inconvenient both in terms of practical use and appearance.

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and its purpose is to eliminate the need for strong power on the center pin during disk forming, and to extend the life of bottles, etc. To provide an apparatus for manufacturing a ring-shaped cake for manufacturing a disk with a large hole diameter in which no coating remains in the hole of the formed disk.

As the upper underframe 10 descends, the sliding horizontal frame 13 also descends while contacting the stopper 7a of the loft 7 via the locking piece 15a and the tension spring 15. Eventually, the sliding horizontal frame 13 comes into contact with the stopper 12 to stop its descent, and the upper cover 12 attached to the lower part of the rod 11 is stopped at a predetermined position.

Despite the stoppage of the sliding horizontal frame 13, the upper underframe 10 continues to descend while stretching the tension spring 15, and the lower end surfaces of both wall rings 10a, 10b of the lower part thereof protrude from the lower underframe 3. It stops when it comes into contact with the lower stand made up of the section 4a (see Fig. 3).

In this state, a donut-shaped space surrounded by the lower stand (3, 4a), the inner wall ring lOa, the outer wall ring 10b, and the upper lid 12 is formed. As is clear from FIG. 1, a part of the outer wall ring 10b is cut out, and the protrusion 3b of the lower frame 3 fits into this part, forming a complete annular space. It has become so.

As the sliding horizontal frame 13 stops, the actuating piece 13a attached to the side pushes the switch 14, and the cake material is injected from the cake injection hole 3C leading into the space,
Form a donut-shaped cake.

When the molding of the cake is completed, the cylinder 9 operates to pull up the upper frame 10, that is, the inner and outer mold rings 10a and 10b. At this time, the sliding horizontal frame 13 remains in contact with the stopper 6a due to the tensile force of the fully extended tension spring 15.

45a and 46a are switching valves.

Next, the alignment of the axis of the stopper die and the axis of the lower die of the disk molding apparatus will be explained. First, in FIG. 4, after pulling up the center pin 24 into the frame 16, the cylinder 22 is activated to pull out the lock pin 22a, and the cylinder 17 is activated to lower the lock rod 18 slightly to remove the upper die mounting plate. 19 and the upper mold 2o are pulled out together.

On the other hand, the cylinder 34 is operated to pull out the pin 34a from the hole 33b, the lock portion 31a is loosened to release the pressing force of the flange 33a, and the lower mold mounting plate 33 and the lower mold block 35 are pulled out together.

In addition, before the core stand, the top center 23 and bottom center 37 are removed, the bolt 33c is removed, and the lower mold block 35 is separated from the lower mold mounting plate 33.
Furthermore, all the holes 36a are loosened so that the lower mold 36 can be moved slightly laterally with respect to the lower mold block 35.

Therefore, with the upper and lower hydraulic mounting plates 19 and 33 pulled out as described above, the lower hydraulic system is operated to

Next, the operation of the disk forming apparatus will be explained. 1st
In the figure, the cake C manufactured by the disk cake manufacturing apparatus A as described above is the lower frame.

3, as shown in FIG. 5, when the cake C is fed onto the lower mold 35 with a slight gap, the cylinder 25 works and the center pin 24 descends, entering into the 60+ of the cake C and the tip thereof It fits into the bottom center 37. In this state, when the lower frame 3 is pulled back to its original position, the cake C falls onto the lower mold 35.

Next, as shown in FIG. 6, only the switching valve 46a is opened to introduce pressure oil from the pipe 46 into the hydraulic chamber 44 in the auxiliary cylinder 42, and when the ram 41 is pushed up, the auxiliary piston is 39 and the main piston 29 are also pushed up, and the upper mold 3
Slightly increase 6.

Next, open the switching valve 45a to connect the pipe 45 to the sub cylinder 3.
Pressure oil is introduced into the hydraulic chamber 43 of No. 8. The pressure oil that has entered the hydraulic chamber 43 enters a ring-shaped slit 43a formed above and presses the step surface 39b of the sub-piston 39, thereby pushing the sub-piston 39 slightly upward. The sub piston 39 is pushed
When the ram 41 is bent, its lower end surface separates from the upper end surface of the ram 41, a gap is formed in the frame, and the pressure oil enters the flow path 39a through the gap and reaches the hydraulic chamber 4o of the main cylinder 28. The pressure oil that has entered the hydraulic chamber 40 pushes up the main piston 30 as shown in FIG. 7, presses the lower mold 36 toward the upper mold 20, and forms the cake C into a disk. In addition, as the lower mold 36 moves upward, the center pin 2
4 is pushed back while being fitted into the bottom center 37.

When the press operation is completed, the pressure in the pipes 45 and 46 is removed and the pressure oil in the hydraulic chamber 40 is transferred to the flow path 39a1 and the hydraulic chamber 43.
As a result, the main piston 30 descends due to its weight, separating the lower mold 36 from the gold F1120 and lowering it. Simultaneously with the lowering of the main piston 3o, that is, the sub-piston 39 integrated therewith, the ram 41 also descends to its original position due to its weight, and the lower end surface of the sub-piston 39 abuts the upper end surface of the ram 41, causing the lower mold 36 The disk press-formed in the above manner is held by the holding plate 1a attached to the inside of the rail 1, and as the rail 1 moves, the disk press-formed in the above manner is lowered to its original position. It is removed from the top of the mold 36, and at the same time the next cake C is supplied.

As described above, in the present invention, when manufacturing a cake, a ring-shaped cake is manufactured in which a hole with the same diameter as the disk is pre-drilled in the center, so there is no need to re-drill the hole with a center pin. This not only makes it possible to prolong the life of the center pin etc. by not requiring strong power on the center pin during disk molding, but it also has the effect of making it possible to manufacture high-quality products since there is no test in the center hole of the disk. .
